SPECIFICATION forming part of Letters Patent No. 601,254, dated March 29, 1898.

Application filed March 3, 1897. Serial No. 625,886. (No model.) Patented in England August 12. 1896, No. 17,886, and in Germany October 8, 1896, Nos. 64,544 and 64,545.

To a/ZZ whom it may concern.-

Be it known that we, HERBERT GEORGE HARRIS, commercial traveler, and WILLIAM BLAOKMORE, clerk, subjects of the Queen of Great Britain, and residents of The Crescent, Weybridge, Surrey, London, England, have invented certain new and useful Improvements in Velocipedes, (for which we have obtained patents in Great Britain, No. 17,886,

Io bearing date August l2, 1896, and in Germany, utility patents, Nos. 64,544 and 64,545, bearing date October 8, 1896,) of which the following is a specification.

Referring to the drawings which form a I5 part of this specificatiomFigure l showsdiagrammatically the adaptationfof ourr invention to a cycle of ordinary construction and Figs. 2 to 10, inclusive, details fully described hereinafter.

2o The object of our invention is to dispense with the necessity of employing a pump or inflater separatel from the machine itself. With this object, as shown in Figs. l and 2, we utilize the seat-pillar tube A of the frame of the cycle as the cylinder of the pump or iniiating contrivance, and we lengthen or eX-v tend the tree or stem of the seat-pillar B to serve as the piston-rod and plunger or piston O, provision being made for the air inlet and 3o outlet orifices and the connections by flexible tubing a with the tire-valves. The seat-pillar is secured in place by a clip or collar C,

hereinafter described, so constructed that it can be instantly released and the piston or plunger B raised and lowered in the act of inflating, the operator employing the saddle or upper end of the seat-pillar asV the handle of the pump.

According to our invention the seat-pillar 4o tree or stem B (shown in transverse section,

b, ridges, or perforations formed in or upon the tree or stem of the pillar B, as above described. For ready attachment to existing cycles the clip C is formed with a sleeve or extension E, secured in the mouth of the seattube A by suitable means, such as the usual lugs and bolt CZ. When the clip, collar, or clamp is tightened up, the aforesaid iiat side C or plug or ridge c is caused to close upon and engage with the corresponding iiat side 6o B Aor grooves o or perforations b on the pillar-stem B.

In order to permit of ,the instantaneous tightening or locking and untightening or unlocking of the clip or clamp C, we provide it with a quick-threaded screw D or an equivalent mechanical contrivance-such, for instance, as an eccentric lever, Figs. 8 and 9, or cam and wedge faces, Figs..6 and 7-preferably so arranged that only half a turn or 7o less of the screw D or lever would be needed to obtain the required grip on the seat-pillar. In some instances we may dispense with the grooves b and ribs c, in which case a graduated scale may be provided on the flat side of the seat-pillar to facilitate readj ustment after the pumping operation has been completed.

If desired, in lieu of the clipV C we sometimes may employ an adjustable collar F, Fig. 10, for holding the seat-pillar at the required 8o height and supporting the Weight ofthe rider, in which case to prevent the seat-pillar from turning we form or provide the mouth ofthe seat-pillar tube with a flat side corresponding to the liat side B on the seat-pillar B, or an vear 8 5 g on the adjustable collar F may be added for the same purpose and secured by the lugs d. If convenient, a longitudinal rib and corresponding groove may be formed on the seatpillar and,A tube in place of the :fiat sides B C'. 9o

By this invention the existing parts of the vcyclenot only constitute the cylinder, piston,

and handle of the pump, but the special shapey of the saddletree or seat-pillar insures lthat the peak of the saddle will always point in the required direction and prevent the saddle turning or slipping around. vIn addition the spring clip or clamp enables the saddle to be instantaneously adjusted and locked at any required height, while the grooves or ridges Ioo in the seat-pillar serve to relieve the pressure on the clamping cam or screw.

It will be seen from Figs. 2 and 7 that-the split collar has a Cylindrical extension Which is adapted to iit into the top of the seat-pillar, and this cylindrical extension is divided from the main part of the clip by the kerf or slot 0;, extending horizontally from the periphery of the said parts.

Having now described our invention, what We claim as new, and desire to secure by Letters Patent, is

In combination with the saddle and. its post havin` a grooved flattened face, the tubular part to receive the post, said tubular part havingY a split collar supported at its upper end with means for clamping the collar, said collar having also a attened face with a rib to interlock with the groove in the post and a cylindrical extension divided from the main part of the collar by a horizontal kerf, substantially as described.

In witness whereof We have hereunto set our hands in presence of two witnesses.
